There are also other great books on RPG theory, game design, etc. etc.

What I'm looking for is a book (or failing that, a website) that collects something similar to blogs about games or full reviews/tours of indie or small publisher games.

I'd like to read about "advertisements" on which games to buy, at minimum, but also possibly thoughts behind why the given games exist, what purpose/niche they serve, what they do well (or even do best/better than other games), comparisons between them, etc.
